Often the materials are based on a case that you will gain one skill point each craft. This won't happen, so you will have to buy a few extra materials while you are leveling your Engineering.
If you are low on gold, I recommend you to try this Gold Making Guide, it can help you to make loads of gold.
If you are still leveling your character or you just started a new alt, I recommend you to use a leveling guide. You can level your character to level 120 in 8 days with this guide.

First, visit any trainer in the main cities of old Azeroth - just ask a guard, and learn Engineering.
Gnome characters have +15 Engineering skill because of their passive [Engineering Specialization]. An extra 15 Engineering skill means recipes stay orange 15 points longer, so you can save a lot of gold by doing lower level recipes for 15 more points.
Buy a Blacksmith Hammer from the Blacksmith supply vendor, it's near a Blacksmithing trainer usually.

Engineering has the option at skill level 200 to specialize in Gnomish or Goblin Engineering. You can get the quests from your Engineering trainer. The main difference between both sides is the location of their respective teleporters and the ability of their trinkets. Some items require a specific specialization to use, while other items are crafted by one specialization but are usable by any engineer. Fortunately, most recipes that are crafted by one Specialization can be worn by both.
